What's the difference between the InwallTech ProGold Series and High Definition Series?
Last Updated: 07/25/2013
Great question! But there are a couple parts of this question that we can drill down on.

Some other questions that are like this are:

Will I like the ProGold or HD series?
What makes these two series different?
Am I willing to pay for those differences?

First the technical question.  What is it about them that makes them cost different.  We can use this website to get an objective number to give each.

For our example, let's take the High Definition HD650.2W vs. ProGold M65.1W.

The HD650.2W gets rated on the site here for an index of 91/100 : Inwalltech Review — HD650.2W

We'll do the math ourselves for the M65.1W, looks like it comes in at: 71.5/100.

What makes these two series different?

The biggest difference is the materials that the drivers are made out of.  That's the main reason for the index numbers being what they are.

The HD series is comprised of a Kevlar woofer and a Titanium tweeter.
The ProGold series is comprised of an Aluminum coated woofer and a synthetic soft dome tweeter (simulated silk).

Materials are the MAIN component on record for how a speaker will sound.  And it costs more for better materials.

Will I like the ProGold or HD series?

I don't know that answer...that's where you come in!  If you are really worried about this decision, my suggestion would be to go listen to some speakers.  Don't look at the NAME of the brand, but listen to them.  The one thing you can't hear from a speaker is the brand name printed on it!  

Once you find something you like, find out what it's made out of.  This is your baseline.  You may be very pleased with a basic poly cone with a budget mylar tweeter.  GREAT, you've just saved yourself a bunch of money not being an audiophile!  Or you may realize where your tastes lie.  And that may be something better.  It will cost a little more, but with our stuff, you'll realize that you're paying less for better stuff!!  And that's the whole point of this exercise.
